Job description
About Us
XOXO is a research lab building the interface of intelligence for everyday life. We're a stealth team of hardcore engineers, designers, and researchers discovering solutions to novel problems impacting life outside work.
With a recent breakthrough across infrastructure, architecture, and the model layer, we’re hiring serious builders to develop the interface and application layer that will bring our vision to life.
About the Role
We’re hiring a seasoned Android engineer to build XOXO’s consumer app with a groundbreaking interface for intelligence. This role is for a truly strong engineer who can own the full mobile surface area end-to-end: architecture, performance, polish, and a highly visual design system that feels intentional in every interaction.
You don’t need a specific background—what matters is your drive: you’re relentlessly high-ownership, you move fast without cutting corners, and you want to build a mobile product that sets a new bar for craft and performance.
What You’ll Do
Design and ship the first versions of our React Native app, taking it from prototype to production.
Translate a highly visual design system into reusable components, motion, and interaction patterns with fluid performance.
Build new product surfaces that incorporate modern AI/ML capabilities in ways that feel natural on mobile.
Drive performance work across the app: rendering, startup, memory, battery, networking, and perceived speed.
Set the bar for mobile engineering quality (testing, instrumentation, release discipline) and partner closely across the stack to ship end-to-end.
Skills & Qualifications
Minimum qualifications:
3+ years shipping production mobile apps with a consistently elite quality bar.
Deep expertise in React Native and Swift, with strong instincts for architecture and long-term maintainability.
Demonstrated ability to turn a highly visual design system into a fast, pixel-perfect product UI (components, interaction patterns, accessibility).
Proven track record making mobile apps feel instant under real-world constraints (startup time, rendering, memory, battery, networking) and knowing where to look when things slow down.
High-ownership builder who moves quickly without sacrificing code quality, reliability, or craft.
Excited to work in-office in San Francisco 5 days a week.
Preferred qualifications — we encourage you to apply if you meet some but not all of these:
Experience at an early-stage startup (company outcome doesn’t matter).
Experience shipping in high-velocity consumer categories with rapid growth (consumer social, gaming, other consumer apps).
Comfort bridging into native iOS/Android when React Native needs it.
Experience integrating ML/AI-powered functionality into mobile product experiences.
Advanced mobile media/graphics experience (3D, real-time rendering, audio, video, streaming).
A link to shipped apps, code samples, or technical writing is strongly encouraged.
Logistics
Location: San Francisco, CA (on-site)
Compensation: $250k-$500k expected salary with 1% to 5% equity depending on background.
Benefits: Top tier health, dental, vision benefits, and many other perks.
